BRACE FOR AUGER-BITS AND AUGERQ mammals forming part of Letters PatentNo. 684,722, dated October 15, 190i.

Application filed January 12, 1901. Serial No. 43,044. (No model.)

T at whom it may concern:

Be it known that I, EUGENE S. ROSE, a citizen of the United States,residing at Stockbridge, in the county of Ingham and State of Michigan,have invented new and useful Improvements in Braces for Auger-Bits andAugers, of which the following is a specification.

Myinvention relates to braces for auger bits and angers; and its primaryobject is to provide means for adjusting the brace in all directions,thus adapting it to be adjusted to a great variety of positions andincreasing its utility and efficiency.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawings, forming a part of thisspecification, and its novel features will be defined in the appendedclaims.

In the drawings, Figure 1 is a front elevation of a bit-braceconstructed in accordance with the invention. Fig. 2 is aside elevationthereof. Fig. 3 is a side elevation, partly in section, of aslightly-modified construction of the device; and Fig. 4 is a view inperspective of two of the longitudinally-adjustable arms.

The reference-numeral1 designates a split socket to receive the bit,provided with theusual thumb-screw 2 for clamping the bit in position.The upper end of the socket 1 is formed with an integral extension 3,formed on one face with ratchet-teeth 4, which interlock with similarteeth on the head 5 of the arm 6. The extension 3 of the socket and thehead 5 of the arm 6 are formed with registering openings, through whichextends a thumb-screw 7, held in position by a but- The arm 6 isadjust-ably connected to an arm 9, the latter being grooved throughoutits length to receive the arm 6 and formed at its upper end with aserrated head 10, which is adapted to engage a corresponding head 11,depending from the handle 12. The arms 6 and 9 are each formed with anelongated slot 13, through which extends a thumbscrew 14, held by a nut15.

The ratchet-faced heads 10 and 11 are connected adjustably bythumbscrews 16, provided with butterfly-nuts 17.

The handle 12 is provided at its upper end with a serrated extension 18,which is engaged by a correspondingly-serrated head 19, formed integralwith an arm 20, to which is slidably secured an arm 21, said arms and 21having a tongue-and-grooved connection and being provided with elongatedslots 22, through which extends a thumb-screw 23, provided with a nut24:.

25 designates the handle or breast-piece of the brace, which is securedto the arm 20 by the interlocking serrated heads 26 and 27, formed,respectively, on the upper end of the arm 20 and the lower end of thehandle 25.

The coacting interlocking serrated heads constitute rosette-joints,which permit a wide range of adjustment, and the sliding connection ofthe arms permits the latter to be adjusted longitudinally to lengthen orshorten the distance between the handle 12 and the bit-socket 1 orbetween said handle 12 and the upper handle or breast-piece Thetongue-andgrooved joints between the sliding arms are of angular shapein transverse section, and thus provide a very rigid connection.

In Fig. 3 the brace is so adjusted that the arms 20 and 21 are inhorizontal position and in parallel relation to the lower arms 6 and 9,and in this embodiment of the invention the handle portion 25 isprovided with an arm 28, at the outer end of which is a knob 29,servingas the breastpiece. The opposite end of the arm 28 is providedwith a ring 29, which fits over the upper end of the handle 25 and issecured in position thereon by a washer 30 and nut 31, which engage theupper threaded end of the stem 32 of the handle.

The utility and operation of the device constructed as above describedwill be readily understood.

The slotted arms 20 and 21 and the arms (3 and 9 may be readilyshortened or lengthened as the character of the work to be done mayrequire, and as will be apparent the brace may be adjusted to a greatvariety of shapes and positions, the adjustable rosette connectionsserving to firmly secure the parts in their adjusted positions.

I claim- 1. A bit and an anger brace comprising a bit-socket having anextension formed with ratchet-teeth, a breast-piece having .an extensionformed with ratchet-teeth, ahandle having extensions formed withratchet-teeth, a pairof slotted and adjustable arms each having a headformed with ratchet-teeth and adjustably secured to the bit-socketextension and a handle extension respectively, a pair of slotted andadjustable arms each having heads formed with ratchet-teeth and adjustably secured to the breast-piece extension and a handle extensionrespectively; and means whereby the parts are adapted to be fixedtogether either in alinement or at an angle to each other.

2. A bit and an auger brace comprising a bit-socket having an extensionformed. with ratchet-teeth, a breast-piece having an extension formedwith ratchet-teeth, a handle having extensions formed with ratchetteeth, a pair of slotted and adj ustablearms having a tongue-and-groovedjoint of angular shape in transverse section and having a head formedwith ratchet-teeth and adj ustably secured to the bit-socket extensionrespectively, a pair of slotted and adjustable arms having atongue-and-grooved joint of angular shape in transverse section and eachhaving a head formed with ratchet-teeth and adj ustably secured to thebreast-piece extension and a handle extension respectively, and boltsand nuts whereby the parts are adapted to be fixed together either inalinement or at an angle to each other.

In testimony whereof I affix my signature in presence of two witnesses.

EUGENE S. ROSE,
